We verify all information on this page using publicly available nomenclature standards from The Personal Care Products Council (PCPC), the European Commission's CosIng database and documentation provided directly by ingredient manufacturers. Our analysis is based on technical data from these sources to ensure accuracy and reliability.

What Is Lactobacillus/Data Fruit Ferment Filtrate?

Lactobacillus/Data Fruit Ferment Filtrate is made from ripe dates (Phoenix dactylifera) that are fermented with the friendly bacteria Lactobacillus. During fermentation the bacteria break down sugars in the fruit and release a mix of skin loving compounds such as amino acids, natural acids and antioxidants. Once fermentation is complete the mixture is filtered, leaving a clear liquid rich in these smaller, more bio-available molecules.

Although date fruit has been valued for centuries as food and folk skincare, turning it into a ferment filtrate is fairly new. Brands began exploring fruit ferments in the early 2000s when Korean beauty labs showed that fermentation could boost the potency of plant extracts while making them gentler on skin. Today suppliers use controlled, food grade fermentation tanks followed by fine filtration to create a consistent ingredient ready for cosmetic labs.

You will spot Lactobacillus/Data Fruit Ferment Filtrate in moisturizing creams, hydrating serums, soothing masks, gentle toners, after-sun gels and age support formulas where its conditioning effect helps leave skin soft and comfortable.

Lactobacillus/Data Fruit Ferment Filtrate’s Cosmetic Benefits/Uses

In formulas this ferment mainly serves as a skin conditioner. By topping up moisture levels and smoothing the surface it helps skin feel softer, look plumper and stay calm, which is why formulators often pair it with humectants like glycerin or hyaluronic acid for an extra hydration boost.

Who Can Use Lactobacillus/Data Fruit Ferment Filtrate

This ferment filtrate is generally suitable for every skin type including dry, normal, combination, oily and sensitive skin. Its lightweight watery texture supplies moisture without heavy oils so it will not clog pores for acne-prone users. Those with very reactive or allergy-prone skin should still scan the full ingredient list because any botanical or fermented extract can carry trace compounds that might not agree with everyone.

The ingredient is plant based and the fermentation process does not rely on animal by-products, making it appropriate for vegans and vegetarians as long as the finished formula is certified cruelty free.

No data suggest a risk for pregnant or breastfeeding women when this ferment is applied topically. That said this is not medical advice and anyone who is pregnant or nursing should confirm any new skincare product with a qualified healthcare professional to be safe.

Lactobacillus/Data Fruit Ferment Filtrate does not cause photosensitivity so there is no added need for extra sun precautions beyond daily broad-spectrum SPF.

Potential Side Effects/Adverse Reactions

Responses to skincare ingredients differ from person to person. The points below detail potential side effects that are unlikely in most users when the product is well formulated and used as directed.

  • Mild redness or warmth in very sensitive skin shortly after application
  • Temporary stinging if applied to compromised or freshly exfoliated skin
  • Allergic reaction in individuals allergic to dates or certain fermentation by-products
  • Breakouts in rare cases if the overall formula contains pore-clogging ingredients not related to the ferment itself

If any irritation or unusual reaction occurs stop using the product immediately and seek medical advice if symptoms persist.

Comedogenic Rating

Rating: 0 / 5

Lactobacillus/Data Fruit Ferment Filtrate is water based and contains no heavy oils, waxes or fatty acids that commonly block pores. Its molecules are mostly small humectants, amino acids and antioxidants that sit lightly on the skin then absorb or rinse away. Because it adds hydration without leaving an occlusive film it is considered non-comedogenic.

Suitable for acne-prone or breakout-prone skin.

Keep in mind that the finished product’s full recipe matters; rich creams pairing this ferment with thick emollients could still trigger congestion even though the ferment itself is pore friendly.

Summary

Lactobacillus/Data Fruit Ferment Filtrate is a fermented date fruit liquid that conditions skin by boosting moisture, supplying soothing amino acids and delivering protective antioxidants. Fermentation breaks the fruit’s nutrients into smaller pieces that skin can use more easily, giving a gentle but effective hydration and comfort boost.

The ingredient is not yet a household name yet interest is growing as brands follow the K-beauty trend of fruit ferments for soft healthy-looking skin.

Safety data show a very low risk of irritation or allergy for most users when the product is well formulated and used as directed. As with any new cosmetic, patch testing a small area first is the easiest way to rule out a personal reaction before applying it to the whole face.
